Age of installed thermal (Fossil fuelled) power plants In the next 50 years, 800 fossil fired power plants Will come to their end Installed Capacity GW Somme will be replaced by nuclear power plants or by renewables But their will also be new fossil fired plants… IEA estimate that 600 thermal power plants Will be built before 2030 Age years Research Direction ENGINE MID TERM CONFERENCE, 9-12 January 2007 > 3

Future for EGS in Europe > Vision (2030? 2050?) • Geothermal energy is the preferred renewable baseload energy option in Europe > Necessity for an European programme with an ambitious strategic objective • To improve EGS technology performance and reduce production costs, hence making the huge geothermal resource available to Europe > Some research gaps still need to be filled Research Direction ENGINE MID TERM CONFERENCE, 9-12 January 2007 > 7

Necessary Technology improvements > Identified needs, four years ago • Ability to predict the geothermal resource at the appropriate scale • Reduce the cost of geothermal wells • Cost effective methodology for reservoir stimulation • Efficient Heat extraction and conversion processes > What is the view today? • Engine Mid term conference will be very informative Research Direction ENGINE MID TERM CONFERENCE, 9-12 January 2007 > 10

Conclusions > Geothermal energy can play a very significant role among the CO 2 reduction strategies. > Today ,many geothermal direct uses provide very efficient ways for CO 2 reduction but, only hydrothermal reservoirs of high grade resources are used for power production > EGS technology has the highest potential in continental Europe to increase the contribution of geothermal energy to the reduction of CO 2 emissions > Engine Coordination Action allows a development of European research efforts and support international cooperation Research Direction ENGINE MID TERM CONFERENCE, 9-12 January 2007 > 11
